Abstract

We propose a new tunable laser source concept for multiple-wavelength interferometry, offering an unprecedented large choice of synthetic wavelengths with a relative uncertainty better than 1011 in vacuum. Two lasers are frequency stabilized over a wide range of frequency intervals defined by the frequency comb generated by a mode-locked fiber laser. In addition, we present experimental results demonstrating the generation of a 90μm synthetic wavelength calibrated with an accuracy better than 0.2 parts in 106. With this synthetic wavelength we can resolve one optical wavelength, which opens the way to absolute distance measurement with nanometer accuracy.

Fig. 1

Schematic of the frequency-comb-referenced light source. The beat detection unit (BDU) generates the beat signal between two lasers and feeds the lock box (LB), which contains a phase sensor and a proportional–integral regulator. The two pairs of optical frequencies, ( ν 1 , ν 1 + 450 kHz ) and ( ν 2 , ν 2 + 650 kHz ) , are generated by means of acousto-optical modulators (AOMs).

Simplified sketch of the optical spectrum of the comb combined with the Nd:YAG and the ECLD. The repetition rate of the pulsed laser is f rep = 100 MHz ; f b = 20 MHz is the reference frequency used by the phase-locked loop.
